General description
Acetoxyacetic acid is kinetically stable degradation product of oxidative degradation of 1,3-dialkylimidazolium ionic liquids in hydrogen peroxide/aceticacid aqueous medium assisted by ultrasonic chemical irradiation. It is an intermediate formed during reactions of manganic acetate in glacial acetic acid with benzene (100°C), chlorobenzene, or toluene.
Application
Acetoxyacetic acid was used in preparation of tert-butyl glycolate.
